It was once believed that the dipole, which comprises much of the Earth's magnetic field and is misaligned along the rotation axis by 11.3 degrees, was caused by permanent magnetization of the materials in the earth. This means that dynamo theory was originally used to explain the Sun's magnetic field in its relationship with that of the Earth.
Excelsior, or wood wool. Wood wool, known primarily as excelsior in North America, is a product made of wood slivers cut from logs. It is mainly used in packaging, for cooling pads in home evaporative cooling systems known as swamp coolers, for erosion control mats, and as a raw material for the production of other products such as bonded wood wool boards.
Global distillation or the Grasshopper effect is the geochemical process by which certain chemicals, most notably persistent organic pollutants (POPs), are vaporized and transported from warmer to colder regions of the Earth, particularly the poles and mountain tops, where they condense.
The grasshopper is copper gilded with gold leaf with glass eyes. The vane fell off the building during the earthquake of 1755 which shook Boston. He and his son Thomas repaired it and remounted it. In 1768 Thomas placed a note labeled "food for the grasshopper" in the belly of the grasshopper. It read: Shem Drowne made it, May 25, 1742.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
In 2011 Dynamo [11] was released in beta form allowing first glimpses of directly programming the behavior of hosted components through a drag and drop node interface. This is similar to the way the visual programming language Grasshopper 3d works on objects in Rhinoceros 3D. [12] In 2012 [13] Revit LT [14] became the newest version of Revit on ...
DYNAMO (DYNAmic MOdels) is a simulation language and accompanying graphical notation developed within the system dynamics analytical framework. It was originally for industrial dynamics but was soon extended to other applications, including population and resource studies [ 1 ] [ 2 ] and urban planning.
Grasshopper is a visual programming language and environment that runs within the Rhinoceros 3D computer-aided design (CAD) application. The program was created by David Rutten, at Robert McNeel & Associates. [ 2 ]
